NOVAS FRONTEIRAS TELEJORNALÍSTICAS: O USO DAS IMAGENS DE CÂMERAS DE VIGILÂNCIA NA PRODUÇÃO NOTICIOSA
Get PDFCenas capturadas por câmeras de vigilância são cada vez mais presentes no processo de produção de notícias nos telejornais brasileiros. Partindo desse pressuposto, buscamos apontar, a partir de revisão bibliográfica, os principais aspectos que constituem a relação entre a produção telejornalística contemporânea e o uso de imagens de equipamentos de videovigilância na narrativa noticiosa, tendo como base as discussões existentes em nossa pesquisa de doutorado que se encontra em desenvolvimento no Programa de Pós-Graduação em Comunicação da Universidade Federal do Ceará. Dessa maneira, apresentamos no texto a seguir aspectos conceituais e teóricos, tanto do campo do Jornalismo, quanto referentes à temática da vigilância, que podem nos auxiliar a compreender os motivos para que haja a apropriação de imagens de videovigilância por parte dos veículos telejornalísticos. Como forma de avançarmos na discussão, propomos a hipótese de que o uso do conteúdo proveniente das câmeras de vigilância ganha força no telejornalismo, em tese, ao se vincular a uma pretensão jornalística que se pauta em transpor para a tela da TV a realidade “tal como ela é”, reforçando mitos como o da imparcialidade jornalística
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
La realidad revisada: las imágenes de videovigilancia como elemento de interés periodístico en la producción de noticias televisivas
No full textA cultura da vigilância espalha-se pela sociedade. Os processos de videomonitoramento, enquanto um dos seus elementos, alcançam diversos contextos. No jornalismo, o uso de imagens de câmeras de vigilância tem proporcionado novas dinâmicas para a publicização dos eventos cotidianos. Em meio às transformações midiáticas ocasionadas por tais dispositivos de visibilidade, buscamos neste artigo verificar em que medida o conceito de valor-notícia orienta a seleção jornalística de acontecimentos flagrados por equipamentos de videovigilância. Para isso, realizamos a análise de conteúdo de 53 edições do telejornal cearense CETV 1ª Edição. Por meio do estudo, constatamos, além da recorrência acentuada de situações noticiadas a partir de cenas capturadas por meio do videomonitoramento, a inexistência de evidências de valores-notícia que embasem a seleção dos fatos veiculados.La cultura de la vigilancia se difunde por la sociedad.

Video surveillance processes, as one of its elements, reach varied contexts. In Journalism, the use of surveillance camera images has provided new dynamics for publicizing everyday events. Amidst the media transformations caused by such visibility devices, this article seeks to verify the extent to which the concept of news value guides the journalistic selection of events caught by video surveillance equipment. For this, we analyzed the content of 53 editions of the TV newscast from Ceará CETV 1ª Edição. With the study, we found, in addition to the accentuated recurrence of situations reported from scenes captured by video surveillance, the lack of evidence of news values that support the selection of broadcasted facts
